UNITED STATES PATENT OFFIC MARY F. SALLADE, OF NEW YORK, N. Y.

PLAlTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 242,479, dated June 7, 1881.

Application filed December 10, 1880. (No model.)

To all whom it may concern:

Be it known that I, MARY F. SALLADE, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Plaiting-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to an improved apparatus for effectuating the process of plaiting fabrics by steam, which I have made the subj ect of a separateapplieation forLetters Patent.

It consists in the combination, with the actuating-roller of the plaiting-machine and the endless band carried over it, of a smooth bearing-plate made to extend from beneath said roller and the plaiting-knife back over the steam-chest to the rear roller, the band being led over said plate, in contact therewith, from the one roller to the other. The use of a second plaiting-roller and of a lower endless band and rollers is thus dispensed with, and the apparatus thereby simplified and reduced in cost.

In the accompanying drawings, Figure 1 is a central longitudinal section of the apparatus, and Fig. 2 a plan view thereof with the endlessband and its rollers removed.

Ais the frame of a plaiting-machine; B, its reciprocating folding-blade, and 0 its feedroller, rotating with an intermittent movement. The mechanism for actuating the feedroller and plaiting-blade constitutes no part of my invention, and may be such as is found in the roller plaiting-maehines now in use. In the example illustrated in the drawings the movement of the blade and roller is produced by means of a crank, D, Fig. 2, upon the shaft E, through the intervention of eccentrics upon said shaft actuating one set of levers connected with a pawl, P, to impart an intermittent movement to the feed-roller O, and with a second set of lovers actuating the folding-blade B, to impart thereto its lifting and reciprocating movements,substantially as in plaiting-machines now well known to the art.

F, Fig. l, is an endless band or belt of drilling or other suitable absorbent fabric, which is led over the roller 0 and thence back over a second roller, 0 whose journals are supported in boxes sliding in horizontal ways upon the pillars H H, so as to permit an adjustment of the tension of the belt upon the rollers by forcing the roller 0 outward. This adjustment is obtained by set-screws W W,workin g against the slidingjournal-boxes of the roller, as shown in the drawings.

K is a bearing-plate extending from the one roller, 0, to the second roller, G, of equal width thereto, and whose ends curve down under said rollers, as shown in the drawings. The reciprocating blade B plays upon the curved surface of the front end of the bearing-plate K, instead of upon a lower roller, as in other forms of plaiting-machines. A steam chest or box, M, is placed under the plate K, a short distance in the rear of the feed-roller O, at a level above that of the lower edge of said roller, and the plate K is bent upward over the box and is made to form a continuous curve from the one roller to the other, so that the belt carried over the plate is kept in constant contact therewith. That portion of the plate covering the box tits tightly thereon, and is finely perforated (see at R, Fig. 2) to admit of a free escape of steam through the plate from the vessel beneath. ,Steam is supplied to this chest M from a suitable generator by means of a tube, N.

The endless band or belt F is carried back over the plate K with an intermittent motion by the intermittent movement of the front roller, (J, and bears closely upon said plate or upon the interposed fabric by reason of the upward bend or curve in the plate, as shown in the drawings, Fig. 1.

In the operation of this improved apparatus the fabric to be plaited (see as, Fig. 1) is fed in under the folding-blade B upon the front edge of the bearing-plate K, and, being caught by the blade in its reciprocating movement, is folded and carried, fold by fold, in under the endless band F upon the roller 0. The folded fabric is now caught by the band and carried, with its plaits closely folded and pressed down upon the plate K, along over the entire length of the plate, and is then delivered therefrom out from under the rear roller, 0, as shown at m, Fig. 1. In its course over the plate K the plaited fabric is carried slowly over the perforations It therein and subjected to the action of the steam issuing therefrom. This hot steam serves to set the plaits, so that they will remain fixed when the process is completed, the operation being assisted by the heat of the plate delivered from the steam.

The endless band F bearing upon the fabric not only keeps it in contact with the plate throughout its entire length with a moderate pressure, but serves also to absorb all excess of moisture in the presenceof the steam, so that none is deposited upon the goods to stain them.

The distance between the rollers, as well as the length and width of the intermediate bearing-plate K, may be varied, the width of the rollers and the general proportions of the several parts of the apparatus not being material to the invention;

The use of the fixed plate K, in combination with the feed-roller (J and folding-blade B, by obviating the necessity of a second roller beneath the roller 0, as found in other plaitingmachines, reduces proportionately the cost of this machine. The plaits are secured as fully by the operation of the endless belt F or its equivalent in combination with the fixed plate K as by means of a second roller.

What I claim as my invent-ion is 1. The combination, with the folding-blade B and feed or pressure roller 0 of a plaitingmachine, and with an endless band, F, of absorbent material passing over said roller, of a stationary plate, K, extending under the roller and folding-blade, so that the latter may work thereon, substantially as and for the purpose herein set forth.

2. The combination, with a stationary perforated pate, K, in a plaiting-machine, and with an endless absorbent band, F, moving over and upon the face thereof, of a steam-sup ply pipe or vessel, M, arranged to produce an emission of steam through the perforations in said plate, substantially as and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MARY F. SALLADE.
